Hi,

I am using 16.3.In my design I created many netclass like POWER,CLOCK,DDR data,DDR add, Then I moved the corresponding nets to that class.After that I assigned the netclass to netclass and its working fine untill I am importing the new netlist. After Importing the netlist all the nets are removed from the netclass and its taking as default. I am not changing any net names.

I checked many time while importing only these problem happening. Plz help me

For the Capture / CIS schematic tools, you will need to back-annotate to the schmatic to get Net Class membership and other properties added, otherwise these properties won't be part of the netlist and the nets will be removed from the Net Classes when the netlist is imported.

Thanks for your reply. I found the problem. In SCH some of the nets already definied the spacing and physical property. same net In allegro also definied property. So there is a miss match between SCH and allegro property. I cleared all the property in SCH and imported. Now working fine. Thanks a lot for your support.
